BSR, I see where you're coming from, and yes I left out part of the story. The house that we moved into is an older historic home full of mysteries with decades of wiring from old alarm systems running through the house. This thing is straight of an episode of scooby doo. I've learned that nothing ever happens in this house like I plan. So far we have encountered phantom plumbing that goes into walls and disappears, a buried live electrical service line that the utility company said isnot theirs. I even found a hidden room in the basement this beast! There's a button in the master closet that says panic room, but I haven't found such a room yet. There's even a walk-in bank vault. I would have thought it was the panic room, but there's no air flow in the vault.
There are so many wires, that I want to take my time and figure out which run where and what they connect to. There is no organization...just wires. To give you a sense of amount of wiring: there's 13 doors, 4 floors.. Plus windows, motion sensors, glass break sensors. The last owner didn't bother hooking up most of the hardwired sensors because there are a trillion of them. ADT instead just used a bunch of wireless modules (that are hideous in a old house). I am trying to go back and do it right.
I do already have the relay board hooked up because I use the elk to monitor and close my gates. I have 9 of the doors already wired, but it will really take a lot of time to figure out which wires are connected to the other doors. This is why I am going slowly and trying to keep the ADT system operable as long as feasible.
